What sanding grit is used between coats of Bona Classic?

120 grit final sand of wood; 150 grit between lacquer coats

Bona specifies 120 grit final sand of wood; 150 grit between lacquer coats for intercoat sanding on Bona Classic. Intercoat sanding or screening removes dust nibs, flattens applicator lines, and provides a mechanical key for the next coat. Too-coarse grit leaves scratch showing through; too-fine or skipped sanding weakens intercoat adhesion.
